Toulouse-Francazal Air Base (BA 101), designated LFBF, is a French military airfield located in the southern suburb of Francazal, approximately 10 kilometres southwest of central Toulouse in the Haute-Garonne department. It has served as a French Air and Space Force (Armée de l'Air et de l'Espace) installation for decades. The base has historically hosted aviation training, logistics, and support units. In recent years, parts of the site have been redeveloped for civil and business aviation use as well as light aircraft operations, following a partial reduction of military activities. Francazal does not serve scheduled commercial airline traffic and has no IATA code. Its proximity to the major Toulouse-Blagnac International Airport means civilian passenger operations remain concentrated at the latter facility.
